User Level Security of Blog Posts

Is there some way that I can restrict edit/delete of published posts to the Author only ( and Admin.) I am working to add BlogEngine.NET to an existing Bible Study Group website. Some of these folks have problems turning their computer on. If I leave edit/delete
wide open these folks are sure to get the blog hosed up in no time.

To give you an idea, we are coming off a Yahoo Group Site because that was too complicated for some of them.

The above is my primary issue. Secondarily, any advice on integrating BlogEngine.NET into an asp.net Clubsite Starter Kit site would be MUCH appreciated.

BTW, I have both the Club Kit and BlogEngine.NET up and running on Windows Home Server if I can help anyone else out with that feat.
